CVE-2026-45745 is a high-severity flaw (CVSS 8.0) affecting termix. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Starting in version 1.7.0, Termix Desktop (Electron) disables TLS certificate validation, allowing a machine-in-the-middle attacker to intercept and modify HTTPS traffic to the configured Termix server. This can lead to credential theft and JWT/session theft during login and normal use. As of time of publication, no known patched versions
